South Australia records two new cases of COVID-19

South Australia has recorded two new cases of COVID-19, one of whom authorities say attended a school while she was likely infectious, and a teenager who returned from Victoria late last month.

SA Chief Public Health Officer Nicola Spurrier said it was “unfortunate” that the woman, in her 20s, attended the Adelaide school while she was infectious.

Professor Spurrier said SA Health was in the process of informing the school community before identifying the institution publicly, but said the woman was a student there and suggested it was an adult education facility.

“Unfortunately this person did attend an educational facility in South Australia during the infectious period,” Professor Spurrier said.

“At the moment, we’re making contact with the principal and the school community.

“Once we’ve done that, we will certainly be letting the public know the name of that school, but it’s important that we let that school community know first.”

She said a “pop-up” COVID-19 testing facility would be set up there tomorrow and other close contacts of the woman were being identified.

The newly diagnosed woman, a close contact of a known SA COVID-19 case, is now being isolated in hotel quarantine.

Teenager with COVID-19 arrived on flight from Victoria

SA Health also announced a teenage girl who arrived in Adelaide from Victoria on Sunday July 26 had been diagnosed with COVID-19.

The girl developed respiratory symptoms, fever and loss of smell 11 days before arriving at Adelaide Airport on Jetstar flight JQ 774.

The teenager was tested on July 31 and her positive result came in yesterday.

Professor Spurrier said SA Health had identified seven close contacts of the girl, but the chances she transmitted the coronavirus were low.

“The chances of her being infectious in South Australia are very, very low but we are going to continue to have her in isolation,” she told reporters on Sunday afternoon.

People on the Jetstar flight are being contacted as a precaution.

Professor Spurrier said the two new cases were concerning.

“That second wave I was asked about yesterday, we are seeing it trickle across the border.”

“But we are doing absolutely everything we can from a public health perspective to ensure we don’t have any chains of transmission in our state.”
